Ford Focus Firing Order Diagram – It’s essential to know which lender (or cylinder Top) is # 1 to help decide a place to start for firing order or perhaps to exchange the right aspect, just like an Oxygen sensing unit, gas injector or ignition coil.
Before everything was required to determine which banking institution or cylinder go is number one was to determine which cylinder head is positioned the farthest ahead. One that is considered the most forwards (closest to the leading of the engine) is the top cylinder and that side is bank a single.
However, many engines these days have cylinder heads that are positioned evenly, that makes it tougher to find out which is banking institution # 1 and which happens to be bank number two. A number of popular good reasons we should know this, for example is usually to determine Oxygen indicator to switch when you would like B1 S1 (Lender One Detector A single), or if you’re attempting to find an ignition coil to examine for a P0301 (#1 cylinder misfire saved) misfire code.
